It's nice, it's even faster than Win8 on this (very constrained) hardware.

Modern UI applications (aka Metro applications) are rendered a bit smaller, presumably to work around the fact that Windows 10 runs on 600 px tall screens, versus the 768 px minimum of Win8 (there were 1024x600 Win8 devices, but they used display driver trickery to emulate a higher density). They also aren't getting out of the way of the on-screen keyboard properly, annoyingly. Win32 apps don't get out of the way of the on-screen keyboard at all. Universal apps, however, behave properly.

Otherwise, it's really nice, and Win32 applications playing nicely in the (easy to run applications side-by-side) Tablet Mode (other than the aforementioned keyboard issue) makes a world of difference - in fact, I'll be running Tablet Mode all the time on this machine, even when I use a bluetooth keyboard+TrackPoint with it (which is most of the time).

Oh, and my annoyance about the keyboard not having PgUp and PgDn is still intact.

Just saw The DUFF! Likeable highschool romantic comedy with good script and a good cast. It kinda feels incomplete, but the humour's good and both Amell and Whitman are really just so damned... likeable... and the flaws are more than overshadowed by their chemistry.
